JOHNSON, OF CIEAWFORDSVILLE, INDIANA, ASSIGNOR TO JOHNSON HAN'U- FAGIUBING COMPANY, OF CRAWFORDSVILLE, INDIANA, CORPORATION" WATER sorr'nnnn Application filed December 22,1928. Serial No. 327,797.

This invention relates to a water filter and/or softener, particularly of the domestic type employing a gravel, silicate or zeolite filtering and/or softener bed.

such a device with a non-cloggingnozzled bed support. The principal feature of the invention'consists in forming a non-clogging nozzle by providing radially disposed open groovesin the exposed ends of the tubular nozzle body, said grooves at their inner ends having free communication with the central channel through said body.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims y In the drawings Fig. 1 is a perspective view of a water softener embodying the invention, parts being broken away to show other parts in detail. 2'is an enlarged longitudinal sectional view through the nozzle supporting plate and associated construction. Fig. 3 is an enlarged perspective view of one form ofnozzle embodyin the invention. Fig. 4 is a similar view 0 the nozzle in inverted position. y,

In the drawings there is shown a tank or container 10 suitably. supported and including near its base and in spaced relation therewith a supporting perforated bed plate 11' may support a layer of gravel 12 in turn supportin a layer of sand 13 which in turn supports t e zeolite bed 14. Such a bed arrangement constitutes a combination water filtering'and softening bed. The hard water supply is indicated at 15 and the water is introduced to the tank beneath the plate 11. The water passes upwardly through the perforations, 1n the plate and thence upwardly through they gravel, sand and zeolite to the" service pipe 16 in a softened condition.

I The plate 11 is aperturedat 17 to provlde a plurality of openings. Each aperture is threaded to receive a nozzle. Each nozzle mcludes a tubular body cportion 18 havin the:

longitudinally directe central ehanne 19. The exterior surface ofthe body 1s threaded flange 21 has squared faces 22 for tool engagement. Six faces herein form a hexagonal head suitable for wrench engagement- V whereby each nozzle may be screwed. into The object of the invention is to provlde face grooves 23; The grooves are shown extending in radial relation, pairs being in diametric alignment. Theinner ends of said grooves communicate with the central channel l9 .of'the body 18. The provision of the open faced grooves insures free passage of the liquid to or from the longitudinal channel 19. If a particle of material should seat over thecontrol channel 19 or transversely fill and cut off one of the radial grooves, another groove or other grooves will provide the necessary communication. grooves are open faced and are relatively deep, complete clogging is eliminated. Since opposite ends are grooved there is no complete clogging even with reverse flow.-

The invention claimed is:

1. In a water conditioning device having a Since the perforated plate for sustaining the water con- .ditioning bed, a plurality of non-clogging nozzles mounted therein and extending therethrough having a channel therethrou h, and a plurality of open face grooves 'exten ing substantially transverse of each nozzle and comcentral channel, anexposed head on each of said nozzles, and a plurality of'open face grooves extending radially of said head in communication with said channel, said grooves being formed in the exposed surface ofsaid head.

3. In afwater conditioning device having a perforated plate .fonsustaming the water conditioning bed, a non-clogging nozzle body receivable by a late perforation and having a longitudinal ell posed tool engageable portion on said body,

annel therethrough, ex-

and a plurality of open face grooves substantially transverse of the longitudinal channel and communicating at their inner ends therewith, said grooves being formed in each oppo} site exposed end of the nozzle body. 4. A non-clogg'in tubular nozzle body including a longitu inal channel extending therethrough, and a/plurality ofradiall extending en face grooves in each expose end of the b0 y communicating at their inner ends' with the longitudinal channel and terminating at their outer ends with the peripheral surface of the nozzle.

5. A non-clogging tubular nozzle body ineluding a longitudinal channel extending therethrough, and an open faced groovein the exposed end of the body communicating at its inner end with the longitudinal channel and terminating at its outer end with the-pev ripheral surface of the nozzle.- 7 In witness whereof, I have hereunto afiixed my signature.
